MENDEL PIANKO, OF VVOODHAVEN, NEW YORK, ASSIGNOR TO NORTH AMERICAN LEATHER COMPANY, A CORPORATION OF NEW YORK.

LEATHER.

SPECIFICATION forming part of Letters Patent No. 704,707, dated July 15, 1902. Application and April 21, 1902. Sierial to. 103.863. (No model.)

To all whom it may concern:

Be it known that I, MENDEL PIANKO, a citizen of the United States, residing at Woodhaven, in the county of Queens and State of New York, have invented certain new and useful Improvements in Leather, of which the following is a specification.

My invention is in the nature of a new article of manufactureto wit, a pebbled leather-made by the process set forth in my application for United States Patent filed August 26, 1901, Serial No. 73,310, which leather is pebbled or grained in varying designs and configurations. By my method of manufacture the finished product may be pebbled with any configuration or design within the imagination and after boarding, as known to the trade, will appear as if the configuration used was of the natural grain of the leather. This is especially true as my method of manufacture does not interfere in.

the slightest degree with the natural grain of the leather, the boarding causing the natural grain to appear through the pebbling, giving the finished article the full natural grain throughout.

My invention is illustrated in the accom panying drawings, wherein Figure 1 isa plan View of a section of leather pebbled in accordance with my invention. Fig. 2 is a section of the same. V

In carrying out my invention l first form from scraps of leather, preferably scraps from the flesh split of a hide, pieces of the configuration desired and secure them in regular or irregular formation to the split of leather forming the base of my article, then coat the surface of this base, with they configurations attached, with cement, and also cement the surface of a thin split or strip of fabric to be used as a surface for the article, then secure the cemented surfaces together by suitable pressure, and, finally, after dryingl board the whole, which results in causing the configuration to appear through the thin surface strip and also causing the natural grain of the base to appear through the surface strip and through the pebbling.

In the drawings, 1 represents the base, preferably the flesh split of a hide; 2, the thin or surface strip of the article, preferably the leather split, known as buffing, and 3 the intermediate pebbles, which maybe of any configuration desired and are preferably made of scraps from the flesh split of a hide,

which, owing to its rough and porous surface,

is more readily and securely fixed by the cement. The leather thus produced is offull natural grain pebbled in any design or arrangement of designs and when boarded has the appearance of a full-grain leatherin which the pebbling appears as a part ofthe grain.

In the manufacture of pebbled leatherssuch, for example, as for the upholstery trade-I may cut the pebbles from a leather having vitally-different grain characteristics from the base of the completed article, in which event boarding would not only produce the grain of the base in thesurface strip, as hereinbefore described, but the grain of the pebble would also appear in the surface strip, giving the completedarticle a varied grain pebbled in fanciful design, and therefore unique and particularly desirable as a furniture-covering.

Myinvention is designed, primarily, to furnish'pebbled leathers of particular or fanciful-design from which electrotypes may be made to enable leather manufacturers to make arfinished article of leather by embossing in the usual manner. It will be apparent, however, thatl make a leather having distinctive pebbling; and without a counterpart, which when made up into an article,as a pocketbook or satcheh'gives it adistinctive characteristic which cannot be obliterated or counterfeited, enabling the article to be recognized at once, the advantages of which will be at once apparent.

It is of course understood that the pebbles or configurations may be of any design-such, I

for example, as flowers, animals, stars,crosses, initials, full names, monograms, or particular trade-marks, dtc.that such pebbles maybe made to order to supply an individual manufacturer, or a single piece of leather may be pebbled in a particular design for an individual. In fact, my invention enables me to produce a leather of full natural grain and strength and wherein pebbling of any design whatever will appear as apart of the grain.

While I have shown and described and preferably used a split of thin leather as a surface strip for the finished article, "I do not desire to limit myself thereto, as silk or other fabric may be used, it being understood that in the use of such fabric after boarding the full natural grain of the base or flesh split will show through the fabric surface the same as through the leather surface, producing, for example, a silk-surface article in full natural leather grain with any fanciful pebbling desired;

What I claim as new, and desire to secure by Letters Patent of the United States, is

1. As a new article of manufacture, 'a pebbled leather comprising a base or bottom layer or fabric, an intermediate layer consisting of leather pebbles of fanciful configuration, and a finishing or top layer, the whole being united by cement and boarded.

2. As a new article of manufacture a pebbled leather comprising a: base or bottom split of leather, leather pebbles of fanciful configuration secured upon the surface thereof, and a surface layer or fabric secured upon the base inclosing the pebbles, the Whole being cemented and boarded.

3. As a new article of manufacture, a pebbled leather consisting of pebbles secured between two layers of leather.

4. As a new article of manufacture, a pebbled leather consisting of pebbles secured between two splits of leather.

Witness my hand, this 17th day of April, 1902, in the presence of two subscribing witnesses.
